Contrary to belief, everything that crawls is not a bug. True bugs belong to the order Hemiptera, which have
needle-like or beak-like mouth parts that are used for piercing and sucking.
The stonefly has neither of these parts
therefore is not a bug, but belongs to the order Plecoptera. So don't screech or stomp but enjoy its beauty
for it is a major source of food for trout.
Look for hatches along steam banks with rapids.
